fix the wire,and then connect it to the device.
⚫ The antenna needs to be led out of the device to prevent signal shielding.
三、Multiple Work Modes
◆ Load Wiring
The diverse load situation corresponds to different wiring ways. In addition, if
the immersion heater doesn't have a temperature sensor, and the GroBoost
needs to use the temperature sensors (Pt1000). The following table 3-1 shows
the wiring diagram of a diverse load situation.The following figure is the overall
detailed wiring diagram.

Wiring ways
The power input line is for phase L1 input
terminals, loads are for phase L1 output
terminals, PT 1000 is for the T1 terminal, which
is linked with the load in the phase L1
Three-phase power
single-phase loads are connected separately to
phase L1/L2 output terminals. Phase L1 is
linked with the PT1000 of the T1 terminal,
Phase L2 is linked with the PT1000 of the T2
terminal
Three-phase power line input, and three
single-phase loads are connected separately to
phase L1/L2/L3 output terminals. Phase
L1/L2/L3 is linked with the PT1000 of the
T1/T2/T3 terminal
Three-phase power line input, and a
three-phase loads are connected to phase
L1/L2/L3 output terminals. Three-phase load is
linked with the PT1000 of the T2 terminal
Three-phase power line input, L1 output
connected relay input, a single-phase load is
connected to the Relay OUT2 .Single-phase
load is linked with the PT1000 of the T1
terminal. Three-phase load is connected to the
11
line input, and two
